I can't seem to find my way to either Takoma park or Industrial. They are on my map but I just can't find my way there. Any help?

Where are you now? That's important for us to know so we know where you're having difficulties.

i go there on most playthroughs, you need to get to the vernon square east metro tunnel, that metro tunnel is very linear and goes directly to takoma and its the only way to get to takoma industrial, vernon square east metro tunnel is close to the statesman hotel, do you kow where chevy chase is ? take chevy chase east to vernon square, now chevy chase east has multiple places it goes to but when you go into the chevy chase east metro tunnel stay at track level, it will take you to vernon square and once you come out at vernon square, you need to explore the area, there's lots of super mutants there but lots of hiding places so tke your time and kill the super mutants then you can explore the area until you find the right metro tunnel, its very close to a crater with lot of radiation and a crashed jet plane, and like i said its near the statesman hotel, if you do the rileys ranger quest thats the area.

Oh maybe that is why. I haven't 'discovered' Vernon square east yet and cannot fast travel there. I guess I need to get there first. These are the last 3 places that I haven't been to yet. When I was playing, my missions all got crossed and it was a real mess. I completed the project purity mission and saw the end credits before I had even been to every location. LOL.

:cold:
vernon square is the location for the rileys rangers quest, go to the museum of history and talk to riley and you'll get a map marker, if you've talked to three dog already then you will have chevy chase on your map marker, from chevy chase above ground, head east, its a short walk and you'll find chevy chase east, go down in the metro and get to the bottom where the train tracks are, stay on the track, travel i think its east through the tunnel do not go up steps once you're down below, stay on the track and straight ahead when you're heading east you'll see the exit, its lit up a bit if its daytime and go stright and it comes out at vernon square, there will be 5 or 6 super mutants around prob, there's lots going on at that location, there is a crater there with a jet plane in it and the statesman hotel is there, a hospital is there, a couple sewer things to go in with more loot, but when you see the crater i'm talking about, you're pretty close to the metro tunnel that goes to takoma, vernon east metro is the one that goes to takoma, there's super mutants and mirelurk kings down there, its a bit tough but with enough firepower you'll be fine.

I honestly think I broke the game. I've gone through all the tunnels from metro central and none of them lead to Takoma or vernon square east. Takoma is on the maps in the metro tunnels but the tunnels are either blocked or they lead to places other than Takoma.

Vernon Sq East metro is not easy to locate. It lies between the Statesman Hotel and Vault-Tec HQ. Very easy to overlook.
